Be it known that l., YYILUAM un im 55A N- inn', manager o l pneuinziiie-i ire works, :i sn l jeet of the King oll Great, Britain, residing :if Cuinnor Rozul, Sutton. in 'the County el' Hin'- rey, Eng-land, have invented new .inni imei: l Improvements in or llelziiini; o .lr -nnnn'ii Tire Covers, of which lhe. following i :i spin iiieation.

grezzi mit seen from a, iioi1alv.e'\s, l. lie. in ,nifl of eo. seni emploved with tires haring hesieeii edges. The domed lines e represent, the iii/'fermnl layes ol' canvas employed, o' wh'eh zi eortia onljyT are h'rougl. around l This portion (Shown sis three in nunY ligure, lthough this ninnlizer v 'ies in pra-ctiee) takes the powerful strain which is ex erted upon the @over nt the point g. The re.- inaining or 'inner layers of canvas nre idle. Un the eonrrnry, with the combined headed edge 2nd. enilless Wire it is possible lo utilize :ill the layers ol' mmf-ns to resist slr-eins. It will he seen from Fig. S. hnl while the outer layers of canvas :ire on rl around the outside of the bead c, as before," :nner layers (eher-.fn

i, J in the l three in number) instead of bein free at the ends, as in Fig. 2, are looped rounc the endless Wire d and stitched at h. The inner layers of canvas are thus secured to the inextensible wire d and are able to assist in resisting strains on the tire-cover.

As already stated, the edges of the tirecover made in accordance with my invention are inextensible. Therefore Iuse in conjunction therewith a rim in which one edge, or a portion of it, can be removed.- The rime' is provided at intervals on its under surface with snugs or projections j,and one edge 7c of the rim is cut away through these projections, or this part of the rim may be cast or formed separate from the rest of the rim. The re movable edge 7c may b'e continuous or in segcured upon the Wooden felly n of an ordinaryl v.or suitable motor-car wheel, depressions or recesses being provided on the peri hery of the Wheel Jto-reoei've the snugs j.of the rim i. The bolts m ma be secured to the snugs on the rim-i insteadof the removable edge k, as

shown in Fig. 4, or, as shown in Fig, 5, the

bolts could be loose and passed through the I removable edge c and sorevved into the rimi.

It will be understood that the removable edge of the rim is arran ed at the outside of the Wheel When mounte on the axle for convenience of manipulation.- When made in segments, it may be necessary to remove one or two only of such segments7 andfnot the Whole, to remove or replace the tire-cover.

I declare that what I claim isl. A tire-cover havin beaded edges and a wire embedded in each o said edges, layersof canvas in such tire-cover art of which are secured around the cores oi' the beaded edges and the 'remainder around the Wires in such edges, substantially as described. y

2. Thecombination in a vehicle-wheel havingits periphery provided Withlateral re'- cesses, a channeled rim fitting on said periph# ery and having lugs engaging in the said recesses, said channeled rim bein formed of a stationary part and a removabIe part, bolts passing through the lugs of the removablel and stationary parts tohold said parts together and a cover held in said channeled rim ,-substantially as described.

In testimony vwhereof I have`signed. my

name to this specification in the presence of two Subscribin witnesses.
